New speed limits and signage for Blanchardstown roads and housing estates are to be introduced in August.

On Blanchardstown's rural roads some 80km/h signs will be replaced with new ones indicating drivers must drive at appropriate speeds.

In Blanchardstown housing estates and other built up areas around Blanchardstown provision is being made for slow zones. Currently the legal speed limit in Blanchardstown housing estates is 50kmh.

New signs will indicate to drivers that the limit is 30km/h and will warn of vulnerable people in the area like children at play.
